Version 3.0.1

• Add a check that explicitly tests if the provided interface is public. This is necessary for generating dynamic proxies with Castle.

Version 3.0.0

LegacyWrapper 3.0 is a major rewrite and not backwards compatible to prior versions.

See this blog post for details.

• The old Invoke<TDelegate>() method has been replaced by a much simpler and more type-safe pattern:

// Define a proxy interface with matching method names and signatures
// The interface must be derived from IDisposable!
[LegacyDllImport("User32.dll")]
public interface IUser32Dll : IDisposable
{
    [LegacyDllMethod(CallingConvention = CallingConvention.Winapi)]
    int GetSystemMetrics(int nIndex);
}

// Create configuration
IWrapperConfig configuration = WrapperConfigBuilder.Create()
        .TargetArchitecture(TargetArchitecture.X86)
        .Build();

// Create new Wrapper client providing the proxy interface
// Remember to ensure a call to the Dispose()-Method!
using (var client = WrapperProxyFactory<IUser32Dll>.GetInstance(configuration))
{
    // Make calls - it's that simple!
    int x = client.GetSystemMetrics(0);
    int y = client.GetSystemMetrics(1);
}

Therefore, there is no longer the need to:

• Create a delegate
• Cast result values
• Pass function parameters as array of object
• Supply the method name as magic string

Other things that changed:

• Documentation on classes and methods has been improved
• There are more unit tests now (especially edge cases)

Version 2.1

• It is now possible to load 64bit libraries in a 32bit process:

using (var client = new WrapperClient(TestDllPath, TargetArchitecture.Amd64))
{
    result = (int)client.Invoke<TestStdCallDelegate>("TestStdCall", new object[] { input });
}

• Please note that this will only work if the OS is 64 bit.
• As the second optional parameter defaults to X86, this release should be backwards compatible.

See this blog post for details.

Version 2.0.1

This is a minor release that updates some XML docs.

Version 2.0

This version 2.0 of LegacyWrapper adds a major performance improvement.

The wrapper executable now loads the requested dll only once until disposed.

LegacyWrapper 2.0 is not backwards compatible.

Version 1.1.0

• Add support for ref parameters (values in passed parameters array will be updated)
• Improve error handling (wrapper exe will not crash randomly any more)

If you notice any errors, feel free to create an issue in this repository.

Version 1.0.1

• NuGet package dll is now compiled with AnyCPU (resulted in a BadImageException)
• Add batch file for creating a NuGet package

Version 1.0

v1.0.0.0
